I did get incredulous looks when I hung a "piko-piko hammer" (aka squeaky hammer -- plastic toy shaped like mallet that makes squeaky noise when you strike something with it) next to the server. Once in a while I do hear it being used. And most amusing of all -- I've been receiving far fewer reports of problems since then.
